Heated seats not working.

[spannerrash]

Hi all, hope you are all keeping safe and well in these uncertain times.

It's been a fairly low priority as I'm not really a fan of heated seats but in the interest of trying to get everything working, I think I'll take a look.

Only the front passenger side seat is working. It's been like that since I bought the car 3 years or so ago. I'm pretty handy with my multimeter and so will start working my way through the system over the next few days but was wondering if there are any usual suspects? Are there any common / regular failure modes or is it just "work your way through it"?

Cheers Frank
